PocketWizard has a new Nikon Power Cable that works with the MiniTT1, Plus III and MultiMAX (w/ USB) transceivers. It will allows these transceivers to draw power from any Nikon DSLR that is equipped with a 10-pin remote port.
The PocketWizard transceivers use little power and, according to PocketWizard, have almost no impact on the camera’s battery life. The Nikon Power Cable (PW-DC-N10) is available for $20. You can find it here at B&H Photo.
